工業(yè)風機和鼓風機介紹（中英文）
概述：
OVERVIEW:
許多風機和鼓風機屬于工業(yè)風機、工業(yè)鼓風機、工業(yè)排氣機、排氣鼓風機、工業(yè)冷卻風機、工業(yè)排風機、工業(yè)通風風機、工業(yè)離心風機和葉輪風機的分類。它們都屬于工業(yè)風機的兩種基本類型之一： 離心式或軸流式。
Many fans and blowers fall under the classifications of Industrial Fans, Industrial Blowers, Industrial Exhausters, Exhaust Blowers, Industrial Cooling Fans, Industrial Exhaust Fans, Industrial Ventilation Fans, Industrial Centrifugal Fans, and Impeller Fans. They are all one of two basic types of industrial fans: Centrifugal or Axial.
“工業(yè)”風機一詞沒有明確的定義，但該術語旨在表示滿足工業(yè)操作需求的較重結構的風機。與商用或暖通空調(diào)風機相比，這可能包括使用更厚的材料規(guī)格、更大的軸、延長軸承壽命的軸承、高溫特性、耐腐蝕材料等。
The term "industrial" fan does not have a clear definition, but the term is intended to mean a fan of heavier construction to meet the demands of industrial operations. This may include the use of thicker material gauges, larger shafts, bearings with increased bearing life, high temperature features, corrosion resistant materials, etc. compared to commercial or HVAC fans.
離心式風機或鼓風機使用封裝在渦形外殼中的七種類型的輪子之一?？諝馔ㄟ^殼體入口進入風機葉輪，轉(zhuǎn)動90度并徑向加速離開風機殼體。
Centrifugal fans or blowers use one of seven types of wheels that are enclosed in a scroll shaped housing. The air enters the fan wheel through the housing inlet, turns 90 degrees and is accelerated radially and exits the fan housing.
軸流風機使用具有兩個或多個葉片的螺旋槳，使空氣沿軸向移動通過圓柱形外殼或成型孔板。
Axial fans use a propeller, having two or more blades, to move air in an axial direction through a cylindrical housing or formed orifice panel.
術語“風機”用于描述風機或鼓風機。為了做出正確的風機選擇，必須考慮風機將面臨的以下條件：
? 需要的風量是多少？其額定單位為每分鐘空氣立方英尺 ( CFM ) 或等效公制立方米每小時 ( M3/Hr )。
? 整個系統(tǒng)的靜壓阻力是多少？其額定單位為英寸水位 ( in WG ) 或公制等效單位毫米水位 ( mm WG )。
注： WG或mm WG是空氣流過管道或管道時產(chǎn)生的流動阻力或摩擦力。確保包括其他設備，如過濾器、阻尼器、熱交換器等。
? 通過風機的空氣溫度是多少？
? 風機外的環(huán)境空氣溫度是多少？
? 氣流是潔凈、干燥的空氣嗎？空氣中會不會有腐蝕性物質(zhì)？
? 如果風機將用于輸送物料，請確認以下問題
a. 材質(zhì)是什么？
b. 該材料的重量是多少（磅/立方英尺）？
C. 每分鐘或每小時需要輸送多少磅？
d. 該材料是長條狀還是顆粒狀？
? 氣流中會有濕氣嗎？
? 風機運行的海拔高度是多少？
? 是否有任何東西通過風機可能會爆炸？
? 風機運行的位置是否含有任何爆炸性物質(zhì)、液體或兩者兼而有之？
The term “fan” is used to describe either a fan or blower. To make the proper fan selection, you must consider the following conditions the fan will be subjected to:
? What is the air volume that will be required? This is rated in cubic feet of air per minute (CFM) or the metric equivalent, cubic meters per hour (M3/Hr).
? What is the static pressure resistance through the complete system? This is rated in inches water gauge (in WG) or the metric equivalent, millimeters water gauge (mm WG).
Note: in WG or mm WG is the resistance to flow, or friction, caused by the air moving through a pipe or duct. Be sure to include other such as filters, dampers, heat exchangers, etc.
? What is the temperature of the air going through the fan?
? What is the ambient air temperature outside the fan?
? Will the air stream be clean, dry air? Will there be any corrosive substances in the air?
? If the fan will be used to convey material, answer the following:
a. What is the material?
b. How much does the material weigh, in pounds per cubic foot?
c. How many pounds will you need to convey per minute or hour?
d. Is the material long and stringy or granular?
? Will there be any moisture in the air stream?
? What is the altitude where the fan will be operating?
? Is anything going through the fan that could be explosive?
? Does the location the fan will be operating in contain any explosive material, liquid or both?
軸流風機可用于上述所有參數(shù)，除非使用風機輸送。大多數(shù)離心風機可用于上述任何參數(shù)。但如果輸送物料，則不適合采用前彎（鼠籠）輪的風機。用于輸送物料的更佳離心輪類型是徑向葉輪。如果要輸送的材料又長又粘，例如紙邊或纖維，則只能使用開放式徑向葉輪。
An Axial fan can be used for all the above parameters, except if you will be using the fan to convey material. Most Centrifugal fans can be used for any of the above parameters. However, if conveying material, a fan with a forward curve (squirrel cage) wheel is not suitable. The best centrifugal wheel type for conveying material is a radial bladed wheel. If the material you will be conveying is long and stringy, like paper trim or fibers, only an open radial bladed wheel should be used.
